From Bulbapedia, the community-driven Pokémon encyclopedia.
Tyrogue belongs to Isamu Akai. He is level-headed and the only one of Isamu's team who is actually concerned with training and battling. This often gets him into fights with Clefairy.
History
Isamu Akai met Tyrogue in Volume 11 of the Pokémon Pocket Monsters manga. Since then, he has traveled with Isamu and his two companions in Johto, Hoenn and Sinnoh. During his travels, Tyrogue was shown to be very serious about training. Before going to Unova, Tyrogue was released.
